Panasonic GM1 compared to NEX-5R. Should I consider switch?

Here's how the sensors of the GM1, Olympus E-M1, and Sony NEX-5R compare:

DxOMark Comparisons

As you can see, your Sony's sensor is better at low light than that of the GM1.

Please don't rely on the overall score which is not accurate in most situations. Instead look at the graphs/actual measurements. You will quickly see that all are very close and almost over lapping, so in real life there will be no noticeable difference. Since the question was comparing an M43 lens with a slightly larger aperture to an APS lens, any difference should be erased.

What is amazing is how much better then E-M1 DR is than the 5R proving sensor size does not dictate which is best.

The OP was concerned about low light performance; that is the particular measurement I referenced and NOT the total overall score. The low light rating for the GM1 is 660, whereas the NEX-5R is rated at 910. Are you saying that this difference is inconsequential, and that the NEX is no better at low light shooting than the GM1? (I ask this sincerely, not being an expert at interpreting DxOMark reviews.)

The point I was trying to make to the OP is that instead of spending almost $1000 (US) on a fast wide Zeiss lens, he might "be able to get by" with the much, much cheaper Sony E-Mount 16mm f/2.8 lens for his travels, given the NEX's apparent better low light performance. That combo could tide him over until he figured out if he really wanted to jump ship from NEX to m4/3. And, the 16mm pancake would also meet another of his criteria (that of being small and light).

PS.  I wasn't suggesting he get an E-M1; I had included the E-M1 in the comparison simply because I was curious as to how it stacked up against the 5R, and was too lazy to redo the comparison for the OP with the E-M1 removed.
